The new report finds that the increase in fossil emissions in 2023 has been largely driven by increased emissions in China – without which the global total would have remained approximately flat at 2022 levels.
Total global CO2 emissions – including land use and fossil CO2 – increased by approximately 0.5% in 2023, driven by a combination of a small drop in land-use emissions, but an increase in fossil CO2 emissions.
However, total CO2 emissions remain ever so slightly below the highs set in 2019 and have been relatively flat since 2015.
- The 18th edition of the Global Carbon Budget, which is published today, also reveals:
- Global land-use emissions have likely been falling over the past two decades, driven by decreasing rates of deforestation in Brazil and other countries. However, land-use emissions remain highly uncertain and trends should be interpreted with caution.
- Most of the increase in fossil emissions was from coal and oil. Global coal emissions reached a new record high, though oil emissions still remain below pre-pandemic levels. Gas emissions and those from cement and other sources remained relatively unchanged.
- China’s fossil CO2 emissions are estimated to be up 4% this year, while India’s are up 8.2%. US and European Union emissions are expected to fall by 3% and 7.5%, respectively.
- Emissions from international aviation and shipping have grown by an estimated 11.9% in 2023, reflecting a 28% increase in aviation emissions (as the sector continues to recover from pandemic lows) and a 1% increase in shipping emissions.
- Global CO2 concentrations in 2023 set a new record of 419.3 parts per million (ppm), up 2.4ppm from 2022 levels. Atmospheric CO2 concentrations are now 51% above pre-industrial levels.
